Spain’s Pacma animal rights political party called for Saturday’s protest as part of its “Mission Abolition.”

Pacma has said it will continue to fight to end bull-related spectacles at a national level.

Barcelona is the capital of Catalonia, the powerful northeastern region that outlawed bullfighting in 2010. The ban reflected a growing movement against bullfighting, but also was seen as a step in the Catalan government’s push to break away from Spain.

Pacma has called for more protests to be held in Madrid and other Spanish cities.
